The teachings from the Course are non-dualistic teachings. In the event you return into ancient China or again into India, you would've heard about Advaita Vedanta. Advaita really suggests “not two,” and that is a way of speaking about the fact that there is a oneness which connects us all. https://www.youtube.com/channel/UCTleG6-484F7WHZD0hAjRRw
